Abstract

A process for continuously preparing dialkyl carbonates and diols, comprising the steps of: feeding a cyclic carbonate and an aliphatic monohydric alcohol into a continuous multistage distillation column; conducting transesterification in the presence of a catalyst in either one or both the distillation column or a transesterification reactor which has been connected liquid-tight to the distillation column so as to continuously receive the liquid in the distillation column from the column and to return the liquid to the column after the reaction, and withdrawing a gaseous low-boiling mixture containing dialkyl carbonates from the top of the distillation column while withdrawing a liquid high-boiling mixture from the bottom of the column; and continuously hydrolyzing an unreacted cyclic carbonate in the latter mixture into diols and carbon dioxide. This process enables dialkyl carbonates and high-purity diols to be prepared with a high productivity even when aliphatic monohydric alcohols containing dialkyl carbonates is used as the starting material.
